Spinning out of the events of both Batman/Superman: World's Finest and Shadow War, father and son will do battle in one of the most Earth-shattering tales ever told! Deep in the heart of Lazarus Island, the demonic legacy of the al Ghul family line has at last been freed, and the Devil Nezha is out for blood. To reclaim his total domination over planet Earth, Nezha has supercharged all magic—anyone who dares use it is overcome by a demonic evil that boosts their abilities to dangerous, unpredictable, and in some cases deadly levels!
